Constructor Detail
Face()Constructor
public function Face(vertices:Vector.<Number> = null, uvs:Vector.<Number> = null)

Creates a new Face value object.

Parameters
vertices:Vector.<Number> (default = null) — [optional] 9 entries long Vector.<Number> representing the x, y and z of v0, v1, and v2 of a face
 
uvs:Vector.<Number> (default = null) — [optional] 6 entries long Vector.<Number> representing the u and v of uv0, uv1, and uv2 of a face
Method Detail
clone()method
public function clone():Face

returns a new Face value Object

Returns
Face
containsPoint()method 
public function containsPoint(point:Vector3D, maxDistanceToPlane:Number = .007):Boolean

Tests whether a given point is inside the triangle

Parameters

point:Vector3D — The point to test against
 
maxDistanceToPlane:Number (default = .007) — The minimum distance to the plane for the point to be considered on the triangle. This is usually used to allow for rounding error, but can also be used to perform a volumetric test.

Returns
Boolean
getBarycentricCoords()method 
public function getBarycentricCoords(point:Vector3D, target:Point = null):Point

Returns the first two barycentric coordinates for a point on (or outside) the triangle. The third coordinate is 1 - x - y

Parameters

point:Vector3D — The point for which to calculate the new target
 
target:Point (default = null) — An optional Point object to store the calculation in order to prevent creation of a new object

Returns
Point
getUVAtPoint()method 
public function getUVAtPoint(point:Vector3D, target:UV = null):UV

Returns the target coordinates for a point on a triangle

Parameters

point:Vector3D — The triangle's first vertex
 
target:UV (default = null) — The triangle's second vertex

Returns
UV
setUv0Value()method 
public function setUv0Value(u:Number, v:Number):void

uv0 u and v values

Parameters

u:Number — The u value
 
v:Number — The v value

setUv1Value()method 
public function setUv1Value(u:Number, v:Number):void

uv1 u and v values

Parameters

u:Number — The u value
 
v:Number — The v value

setUv2Value()method 
public function setUv2Value(u:Number, v:Number):void

uv2 u and v values

Parameters

u:Number — The u value
 
v:Number — The v value

setUVat()method 
public function setUVat(index:uint, u:Number, v:Number):void

To set uv values for either uv0, uv1 or uv2.

Parameters

index:uint — The id of the uv (0, 1 or 2)
 
u:Number — The horizontal coordinate of the texture value.
 
v:Number — The vertical coordinate of the texture value.

setVertexAt()method 
public function setVertexAt(index:uint, x:Number, y:Number, z:Number):void

To set uv values for either v0, v1 or v2.

Parameters

index:uint — The id of the uv (0, 1 or 2)
 
x:Number — The x value of the vertex.
 
y:Number — The y value of the vertex.
 
z:Number — The z value of the vertex.
